Title: Vertical synchronizing signal processing circuit
Inventor: ANZAI SHUNICHI
IPC: H04N5/06
Filed: 1990-11-30
Abstract: PURPOSE:To obtain stable vertical synchronizing performance by automatically changing over by which of 1st and 2nd gate pulses a sampling output is gated to a sampling output. CONSTITUTION:The window pulses for gate to be applied on the vertical pulse VP outputted from a sampling circuit 3 are formed in plurality and are automatically changed over by the input state of the vertical synchronizing signal VSync that the window pulse of a narrow width is inputted to a terminal 7 in the stable input state at which the vertical pulses VP are periodically and continuously obtd. and the window pulse of a broad width is inputted in the astable input state at which the above-mentioned pulses are not obtd. Then, the pulse separate from the vertical synchronizing signal VSync is masked even if this pulse is generated by noise, etc., when the periodic and continuous vertical synchronizing signal VSync is obtd. The erroneous recognition of this pulse as the vertical pulse VP is thus obviated. On the other hand, the pulse of the broad width is used as the gate pulse in the case of a phase deviation or the input of the non-standard signal and, therefore, a vertical pull in is executed over a wide range. The stable vertical synchronization performance is obtd. in this way.

Title: Tracking device for optical disk player
Inventor: KAWAKAMI SATOSHI
IPC: G11B7/095
Filed: 1991-11-25
Abstract: PURPOSE:To perform stable tracking servo. CONSTITUTION:The reflected light from an optical disk is received by a photodetector 1, and the phase difference between diagonal sums of light receiving faces 1a to 1d of the photodetector is denoted as a time difference error signal, and the difference signal between two areas divided by a boundary line along the track of the optical disk is denoted as a push-pull error. Match or unmatch between their polarities is detected by a polarity coincidence detecting circuit 14, and a switch SW1 is switched to the side of a switching terminal (a) or (b) by the output of this circuit 14. Then, the polarity of the push-pull error signal is caused to coincide with that of the time difference error signal. Thus, the push-pull error signal and the time difference error signal at the time of opening the tracking servo are mixed with the same polarity independently of the depth of pits. Since these signals at the time of opening the tracking servo are mixed with the same polarity independently of the depth of pits, tracking servo which is strong against offset and has a high gain is performed.

Filed: 1994-12-27
Abstract: PURPOSE: To remove noises from the trace of an optical time region reflectometer(OTDR) by adapting the noise component of the signal, and subtracting the adapted noise from the original signal. CONSTITUTION: A function is defined over the length of an electric signal to characterize the local noise of the signal, and this function given is evaluated locally, and on the basis of the result from evaluation, the noise of the signal is decided locally. This operating cycle is repeated over the length of the electric signal for generating signals in which the decided noise is decreased.
